WINDOW REGULATOR.

Application filed August 25, 1924. Serial No."i34,123.

The invention relates to window regulators and refers more particularly to mechanisms for raising and lowering the windows or closures of vehicle bodies. One of the ob- 5 jects of the invention is to provide a window ways in the door Figure 3 is a cross section on the line 33 of Figure 2;

Figure 4 is a cross section on the line 4- of Figure 3; v

Figure 5 is a perspective view partly in section of a portion of the irreversible driving mechanism.

.As shown in the present instance 1 is the door of a motor vehicle having in its upper portion the opening 2 and in its lower portion the chamber 3. 4 is a window or closure for the opening 2 into the chamberv 3. 5 is a lifter arm suitably connected at itsouter end to the window to raise and lower'the same and suitably connected at its inner or pivotal end to a .toothed member 6 for swinging-the arm.

For the purpose of raising and lowering the window 4 and also maintaining thiswindow in its adjusted positions, I have provided an irreversible driving mechanism between the handle 7 and the toothed member 6. In detail, 8 is an anchorage member suitably mounted upon the door and 9 and 10 are cooperating driving and driven shaft sections respectively connected to the handle 7 and the toothed member 6. The driving shaft section 9 has at its inner endthe poly onal portion 11 which is engageable in a correspondingly shaped aperture in the han dle 7, the adjacent cylindrical portion 12,

' which is journaled in the anchorage memher 8 and the segmental portion13 which is spaced from the anchorage member. The driven shaft section has at its outer end the vertically slidable in guide-- gear member or pinion 14: which meshes with the toothed member 6, the adjacent cylindrical portion 15, which is 'journaled in the anchorage member 8 and the segmental portion 16, which is spaced from the anchorage member. The segmental portions 13 and 16 overlie each other and have the same axis of rotation and their outer periph-- cries have the same radius of curvature.

17 is a pin extendingaxially of the driving and driven shaft sections and preferably having headed ends for connecting these sections to each other. This pin has a diameter equal to the width of the space be: tween the segmental portions 13 and 16 and as a consequence holds these segmental portions in correct spaced relation to each other. I

The drivingand drivenshaft sections 9 and 10 respectively may be readily manu- .factured from a single piece of-stock'which is formed to provide the polygonal portion 11 and the cylindrical portion 12 at one end, the gear member or pinion 14 and the cylindrical portion 15 at the other end, and an intermediate cylindrical portion. This stock is also bored to receive the pin 17. However,

before insertion of this pin 17 the stock, is longitudinally cut by suitable means such as a saw, the slot 19 formed by the cutting terminating short of its ends.

The stock -'is r also transversely cut at' '18 and 20 to separate the segmental portion '13 from the cylindrical portion 15 and the segmental portion 16 from the cylindricalportion 12 respectively, and also to form two separate members, namely the driving and driven shaft sections. The connecting'pin is then inserted and secured in place.

21 is a coil spring having mturned ends opposite sides of the pin 17 in the space between the seg-j 1 22 and 23 on and engaging mental portion driven shaft sections. These inturned ends are ofa diameter less than the width of the space to provide clearance. The convolutions of this coil spring surround thesegthe anchorage member 8 and have an external diameter slightly less than the internal diameter of the anchorage member to provide sufficient clearance to permit rotation of the driven shaft section 10 upon rotation of the inturned ends of the coi spr ng."

mental portions of the shaft sections within s 13 and 16 of the driving and .of the driving shaft section 9 throu h either If However, if the driving shaft section were stationary and rotation of the driven shaft section in either direction were attempted.

v of locking device for retaining a window in its adjusted position and also that I have provided a locking device which may be manufactured at a relatively low .cost.

What I claim as my invention is: 1. In a window regulator, the combination of an anchorage member, a driven member operatively connected to a window, a driving member overlying said driven member, and

a s rin member havin ends freel en a ing between said driving and'driven members, and an intermediate portion between one of said members and said anchorage member and engageable with the latter.

2. In a window regulator, the combination of an anchorage member, a driven member operatively connectedto a w1ndow having a portion journaled in said anchorage member, a driving member having a portion journaled' in said anchorage member and another portion overlying and spaced from a portion of said driven member and a spring member having inturned ends freely engaging the space between the overlying portions of said driving and driven members and an intermediate portion between one of said members and said anchorage member and engageable with the latter.

3. In a window regulator, the combination of an anchorage member, a driven member having a toothed portion for operatively connecting said driven member to the window, another portion journaled in said anchorage member and a segmental portion spaced from said anchorage member, a drivmg member having a portion journaled in said anchorage member and a segmentalportion spaced from said anchorage member'and overlying and spaced from the first mentioned segmental portion, an axial pin connecting said members and a spring member having inturned ends freely engaging in the space between the segmental portions and an intermediate. portion between one of the segmental portions and said anchorage member' and engageable with the latter.

4. In a Window regulator, the combination of an anchorage member, a driven shaft section operatively connected to a window and having a portion journaled in said anchorage member and a segmental portion, a driving shaft section having a portion journaled in said anchorage member and a segmental portion overlying and spaced from said first mentioned segmental portion, a common means for securing said driving and driven shaft sections to each other'and for positioning the segmental portions thereof, and

a s rin havin inturned ends freel en a ing in the space between the segmental portions and an intermediate portion between One of the segmental portions and said an; chorage member and engageable with the latter,

5. In a window regulator, the combination of means for lifting a window including a toothed member, an anchorage memher, a driven section connected to said toothed member and having a portion journaled upon said anchorage member, a driving section overlying said driven section and having a portion journaled upon said anchorage member, and a spring having ends engaging between said sections and an inter- .mediate portion between one of said sections and saidfanchorage. member and engageable with the latter. j

6'. In a window regulator, the combination of means for lifting a window includin a toothed member, and an irreversible driving mechanism therefor which turns freely when actuated to turn said toothed member but which looks when said toothed member is. turned to actuate said mechanism, said mechanism including an anchorage member, a driven shaft section connected to said toothed -member, a driving shaft section overlying and overlying and spaced from said first mentioned integral portion and a member surrounding said integral portions and having inturned ends extending in opposite directions and freely engaging in. the space between said integral portions and also havin an intermediate portion between one of said integral portions and said'support and engageable with the latter.

8. In combination with a support, a driven member having a portion journaled in said support and an integral portion spaced from said support, a driving member having a portion journaled in said support and an integral portion spaced from said support and overlyingand spaced from said integral portion, an axial, opening connecting said driving and driven members and a coiled member having inturned ends on opposite sides of said opening and freely engaging in the space between said integral portions,
